Creating an Application Crash Dump

How to Create User Mode Crash Dump Files

If you experience application crashes you may be asked by support to create a crash dump file. Crash dumps are created automatically by Windows if the following registry key is present:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps

In order to help support troubleshoot your problem please do the following:

  1. Create the registry key LocalDumps if it is not present already.
  2. Reproduce the problem (i.e. make the application crash).
  3. Locate the crash dump file in %LOCALAPPDATA%\CrashDumps. Note that if the crashing application runs under the System account, that resolves to C:\Windows\System32\config\systemprofile\AppData\Local\CrashDumps.
  4. Send the crash dump file to support.

This works on all versions of Windows beginning with Vista and Server 2008 (including Windows 7, Windows 10, Server 2016, Server 2019, etc.).
